PORTABLE TENT.

Specification of Letters Patent.

Patented J uly 22, 1913.

Application filed J une 19, 1912. Serial No. 704,690.`

'o ali ywhom it may concern:

Be it known that I, FREDERICK WILLIAM lirfrrnr., a subject of the King of Great Britain, residing at Hadley, lin the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Portable Tents, of which the following is a specitication.

The invention relates to tents, and more particularly to the class of portable tents.

The primary object of the invention is the provision of a tent wherein the center pole is entirely dispensed wit-h thereby obviating obstructions interiorly of the tent when erected. i

Another object of the invention is the pro-visioii of a tent wherein the props therefor are adjustably connected so that the size of the tent may be varied according to the uses desired thereof.

Another object of the invention is the provision of a tent in which the props or frame thereof can be knocked down and brought into compactform so that it may be placed or stored in the least possible space or conveniently transported from one point to another when knocked down.

A. further object of the invention is the provision of a tent, wherein the frame or props thereof may be conveniently anchored without depending upon ropes and pegs for supporting the saine.

A still further object of the invention the provision of altent which when set up or ready for use can be shifted from one point to another without requiring the collapsing thereof or disassembling of its parts.

A still further object of the invention is the provision of a ten-t which is simple in construction, strong, readily and easily set up or knocked down and one which is inexpensive in manufacture.

ll/Tith these and other objects in view the invent-ion consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated `in the accompanying drawings, and pointed out in the claims hereunto appended.

ln the drawings: Figure 1 is a front elevation of a tent constructed in accordance with the invention, the saine being shown set' up. Fig. 2 is a vertical longitudinal sectional view thereof. l? ig. 3 is a top plan view. Fig. 4 is an elevation of the frame of Ethe tent showing thc canvas removed. Fig. 5 is a fragmentary side elevation of one of the hinged joints of the frame. F ig. 6' is a fragmentary vertical longitudinal sectional View through one of the props. F ig. 7 is a fragmentary perspective view of a modified form of tent, the same being shown set up. F ig. 8 is a vertical transverse sectional view thereof. l

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings by numerals, the tent comprises a k-nockdown frame including a center coupling 10 formed with downwardly diverging socket extensions 11 having fitted therein inner tubiforin sections 12 in which fit outer telescoping sections 13, the inner sections 12 being provided with clam-ping collars 14 having the usual bind-- ing screws 15,'whereby the said outer sec tion 13 inaybe held in extended adjusted position for increasing or decreasing the size of the tent frame. Swingingly con'- nected to the outer ends of the outer sections 13 are the inner tubiform sections 16 of vertical props or legs, the outer sections 17 of which telescope within the said inner sections 16, the said outer sections being held adjusted within the latter by means of clamping collars 1'8 carried by the said sections 16 and are provided with the usual binding screws 19. The outer sections 17 of the props or legs are formed with pointed free ends 20 which are designed to be driven into the ground for the anchoring and mounting of the props therein.

The inner sections 16 of the props near their upper ends are detachably connected for swinging movement to the outer sections 13 by means of removably pivoted pins 21, while detachably connected with the said upper ends of the inner sections 16 of the props is the canvas covering 22 of the tent, the said cover being also connected with the center coupling 1() which is formed with a crown head 23 forming a bearing for the canvas 22 when connected thereon. Pivotally connected to the upper ends of the section 16 of the props are arcuateshaped` braces 24e, each being rovided with a series of openings 25 througi any one of which is adapted to be passed the securing pin 26 which is designed to engage the outer section 13 adjacent thereto of the top portion of the tent frame, so as to prevent the collapsing of the latter, or the folding of the props when the tent has been set up ready g incassa for use. Formed in the upper ends of the inner sections 16 of the props or legs are stop members 27 against which rests the canvas 22 so as to prevent the lowering ot' the same upon the said props or legs, and also to obviate the sagging of the canvas at the top of the frame when the tent is set up :tor use.

In Figs. 6 and 7 there is shown a slight modification of tent wherein the center couplings 28 are formed with downwardly diverging opposed socket. extensions or branches 29 inwhich are fixed the inner sections 3G of the top supports for the tent, which supports are each of the identical construction hereinbeore described, but are arranged in spaced relation to each other transversely of the tent throughout the length thereof. Uniting or connecting the center couplings Q8 in series are extensible union bars comprising tubiform sections 3l and telescoping sections 32 which latter are adapted to telescope within the tubiform sections 3l both sections being securely fitted to the center coupling 20, so as 'to lie in a horizontal plane. The tubiform couplings 3l are provided with clamping rings 33 having binding screws 34, so that the telescoping sections 32 may be locked in adjusted position it being seen that the tent frame may be extended or shortened for varying the size thereof as may be desired;

rlhe frame which is of the knock-down type supports a canvas covering 35 which is mounted thereon as shown although the same may be mounted in any other manner if desired. It is deemed needless to describe in detail the manner of collapsing or bringing the tent to knock-down position because this operation can be clearly comprehended from the drawings which illustrate the detail construction of the invention and therefore an extended explanation has been omitted.

From the foregoing description, taken in connection with the accompanying drawings it is thought that the construction and operation ot the invention will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. A portable tent comprising extensible legs, having pointed lower ends, a substantially inverted t -shaped coupling, sectional extensible members engaged in a pair of the branches of the coupling, a bearing formed on the remaining branch of the coupling, forks fixed to the outer ends of the members and pivotally connected near the upper ends ot 'the legs, arcuate shaped braces pivotally connected to the legs and adjustably connected to the said members, and a covering having openings receiving one branch of 'the coupling and the upper ends of the legs.

2. A portable tent comprising extensible legs, having pointed lower ends, a substantially linverted if-shaped coupling, sectional extensible members engaged in a pair ot' the branches of the coupling, a bearing formed on the remaining branch of the coupling, forks fixed to the outer ends of the members and pivotally connected near the upper' ends ot the legs, arcuate shaped braces pivotally connected to the legs and adjustably connected to the said members, a covering having openings receiving one branch of the coupling and the upper ends of the legs, and bearings formed on the upper ends of the legs and engaged with the covering.

8. A portable tent comprising extensible legs, having pointed lower ends, a substantially inverted Y-shaped coupling, sectional extensible members engaged in a pair oi the branches of the coupling, a bearing formed on the remainingbranch of the coupling, forks fixed to the outer ends of the members and pivotally connected near the upper ends of the legs, arcuate shaped braces pivotally connected to the leOs and adjustably connected to the said members, a covering having openings receivingl one branch ot the coupling and the upper ends ot the legs, bearings formed on the upper ends of the legs and engaged with the covering, and means for locking the sections of the members and legs in adjusted position.

In testimonyr whereof l atiix my signature in presence of two witnesses.
